ABSTRACT:
A powdered substance, which is suitable for preparation of a beverage with an extraction fluid and which is compacted in a form of a cake, is extracted for preparation of a beverage. The compacted substance cake is contained within a sachet between two sachet sheets which, prior to extraction of the substance, protect the substance against oxygen and water vapor and which extend to sealed edges for containing the substance within the sheets prior to and during extraction. In effecting extraction, one sheet is perforated first to provide at least one opening for injection of extraction fluid, and extraction fluid is injected under pressure into the sachet for contacting the substance and for extracting the substance in the sachet, and the other sheet advantageously is deformed against a surface having portions forming, upon deformation of the second sheet, local breakages in that sheet for opening that sheet for flow of extracted beverage substance. The cake and sheets advantageously are configured so that there is free space between at least one of the cake surfaces and one sheet for allowing the substance to expand between the sheets, and the cake surface positioned adjacent the sheet which is opened for injection of extraction fluid may have a concave shape or may have channel impressions therein.
